Description
Technical field
The utility model relates to a kind of dust cup of dust collector.
Background technology
As everyone knows, dust catcher is by motor of dust collector High Rotation Speed, sucks air from suction inlet, and produce vacuum at the ante-chamber of dust catcher, external atmosphere pressure is higher than dust catcher inside, and suction inlet is by the air intake of ground with dust.Along with the revolution of the impeller be connected with motor shaft, the air flue of the air in dust storage chamber in body flows to exhaust portion, and air pressure increases, and the dust of suction is filtered by filter, and clean air is discharged and cooling motor.Usual dust catcher comprises traditional dirt bag type dust collector and dustless bag type dust collector two kinds.
Traditional dirt bag type dust collector, relies on the filtration filtered air of paper bag or cloth bag itself.Air is discharged by the Minute pores on paper bag after entering dirt bag, and dust paper scrap etc. is then stayed in dirt bag.After long-time use, dust can be attached on dirt bag inwall and block the discharge of pore obstruction air, causes the suction of dust catcher to decline.If change dirt bag not in time after dust suction, the bacterium in dust, acarid etc. also can in dirt bag amount reproduction, when next time uses, bacterium acarid will produce peculiar smell along with air-flow is discharged in air, causes secondary pollution, affect user and household's health.
Dustless bag type dust collector is also known as the cup type dust catcher of dirt, air is utilized in dirt cup, to rotate the high speed centrifugation power of formation to be separated dirt gas, dust falls in dirt cup due to Action of Gravity Field, decrease blocking, horizontal suction is powerful lastingly, the air be separated is discharged after then filtering via electric motor protecting filter and efficient HEPA (High Efficiency Particulate Air high efficiency particle air filter), not dust-laden mite, stop secondary pollution, and need not often change dirt bag, therefore dustless bag type dust collector progressively replaces dirt bag type dust collector, obtain the favor of numerous dust catcher user, also Ge great dust catcher manufacturer is impelled dustless bag type dust collector to be carried out to the research and development of continuation.Existing vacuum cleaner without dust bag usually adopts and arrives dirt cup side air inlet mouth from the main suction inlet of front end along air intake passage, be incorporated into primary separator again, first time separation is carried out by whirlwind guard, then carry out secondary separation through multiple whirlwind cone, but this structure wind inlet channel is long, increases die cost, efficiency loss is large, easy plug-hole, hair is easily wrapped on whirlwind guard, needs manually dress to get one-level chorista during cleaning.
